FDA ingredient list order: descending weight

The short answer

US ingredient lists run in descending order of predominance by weight at the time of manufacture. Water counts. Compound ingredients should be broken out when they contribute allergens or when FDA’s compound-ingredient rules require it. A pretty order that leads with “Madagascar vanilla” when sugar dominates is not a legal order.

Where this shows up in a real kitchen

Home cooks write recipes in the order they add things to the bowl. FDA lists are not method steps. If you scale a cookie dough and butter overtakes flour, the list order changes even if the method does not. Ice in a blender drink becomes water in the list.

The US rule

21 CFR 101.4 governs ingredient statements. Ingredients are listed by common or usual name in descending order of predominance. Sub-ingredients of a compound food appear in parentheses after that compound’s name when required. Spices, flavors and incidental additives have limited exceptions — sesame is not an incidental additive when you sprinkle it on purpose.

How to apply it

Weigh the batch as mixed, not as purchased if yields change (cooked onions lose water). Sort heaviest first. Expand chocolate, soy sauce, pastry and seasoning blends so major allergens are visible. Keep the same order on the Nutrition Facts serving calculation’s recipe, or the two panels will drift.

1. Weigh each ingredient in the finished batch, converting cups to grams once.
2. Sort descending; include water and cooking liquids that remain.
3. Expand compound ingredients that carry major allergens.
4. Re-sort whenever a seasonal swap changes which ingredient is heaviest.

Worked example

A 10 lb batch of tomato basil soup: tomatoes 6 lb, water 2 lb, cream 0.8 lb, onion 0.5 lb, olive oil 0.4 lb, basil, salt, garlic. The list begins “tomatoes, water, cream (milk), onion…” not “fresh basil, heirloom tomatoes”. Cream declares milk. If you later add a wheat-based roux, wheat enters both the order and Contains.

Listing ingredients in the order you shop

Produce first, spices last because that is how the walk-in is organized. Predominance is weight, not shelf location.
